Abstract: The invention relates to a method and a screening apparatus (1) for screening pulp. In the method, the maximum length of fibres and shives flowing through holes (4a) in a screen drum (4) is adjusted by moving blades (8) with a sharp front edge close to the sur­face of the screen drum (4) in such a manner that the sharp edge (8a) of the front face moving closest to the drum surface strikes shives or long fibres passing through the hole (4a) and pulls them back. The rate of travel of the blades (8) is so adjusted that the pulp flows in the hole (4a) only over a dis­tance corresponding to the predetermined fibre length during the interval between the front edge of two successive blades (8). The screening apparatus (1) comprises blades (8) moving in parallel with the sur­face of the screen drum (4). The front edge of the blades defines in cross-section a sharp angle, the point of the angle defined by the front edge moving closest to the surface of the screen drum (4).

Abstract: 2. It is intended to develop an easily assembled system consisting of double-walled pipe elements which can be produced individually at the works and whose ends are precisely circular and which can thus be welded together to form a pipeline system, without using any special clamping device. This object is achieved by means of double-walled pipe elements which are characterised in that   a) a centring ring is fitted on each of the two ends between the inner pipe and the outer pipe; b) a connecting ring is welded to each of the two ends, which ring connects the inner and outer pipe rigidly to one another and c) if necessary spacer rings are fitted as spacers to the inner pipe.   Such double-walled pipe elements are suitable for the assembly of pipeline systems in which corrosive fluids are conveyed.

Abstract: A paper feeding control device in which paper sheets delivered from paper containing sections (12, 13, 14) are stopped when their front ends are detected by paper detecting means (24, 25, 26). The paper sheets are subsequently fed from the position where they are stopped. The subsequent paper sheet is delivered at intervals of time (tl) corresponding to a minimum required spacing between paper sheets. Accordingly, even if the spacing between paper sheets is decreased to a desired spacing or less by slip of the paper sheets during feeding, the paper sheets do not collide with each other and the paper jam or the like does not occur. In another embodiment, in continuously feeding paper sheets, two conditions, that is, the elapse of time (t2) corresponding to the ideal spacing with which paper sheets are fed and the elapse of time (tl) corresponding to the required minimum spacing between paper sheets are ANDed, to control the timing of starting to feed the subsequent paper sheet. The paper sheets continuously conveyed are always suitably spaced apart from each other. Accordingly, even if the ends of the paper sheets are out of line with each other in a paper containing section (12, 13, 14) and the paper sheets are delivered   slightly earlier or later at the time of starting to feed the paper sheets or the paper sheets slip while being fed or conveyed, there occurs no paper jam or the like on a conveying path.

Abstract: A drive circuit (29) for applying a supply voltage (+V) to a sending coil (10) provides resonant coupling of the sending coil (10) with a target coil (34) regardless of changes in the inductance of the sending coil (10), as long as the resonant frequency of the sending coil (10) is greater than the resonant frequency of the target coil (34). A controller (44) provides variable delay intervals in the application of the supply voltage (+V), thereby compensating for changes in the sending coil's (10) inductance with the passage of time and proximity effects. The controller (44) examines the reflected voltage induced in the sending coil (10) by changing currents in the target coil (34) to examine the degree of resonant coupling between the two coils (10, 34) and correct any mistuning.

Abstract: A steering process for road vehicles with front and rear wheel steering is provided, in which the yawing movement is isolated from the lateral movement of the front axle by means of an integrating feedback of a measured yawing speed signal to the front wheel steering, as a result of which the problem with the steering is divided up into two sub-problems which are to be solved separately, namely into a lateral tracking of the front axle by a signal which is generated by a driver with the steering wheel and into an automatic control of the yawing movement, and the inherent values of the yawing movement can be displaced as desired, by feeding back the measured yawing speed signal to the rear wheel steering, in such a way that the selection of the inherent yawing values has no influence on the steering transmission function from the steering wheel to the lateral movement of the front axle. When using the steering process according to the invention, the driver no longer has to worry about the yawing movement of his vehicle at all; this movement is stable. In addition, inherent values of the yawing movement can also be determined as desired via the rear wheel steering and matched to the desired driving style, such as sporty or comfortable.

Abstract: A monofunctional alcohol or acid is used to chain stop a condensation reaction for preparing a low molecular weight unsaturated polyester resin. The monofunctional acid removes terminal hydroxy groups and replaces them with hydrocarbon groups. The monofunctional alcohol removes terminal carboxy groups and replaces them with hydrocarbon groups. The resulting polyester resins have improved hydrolytic stability. These chain stopped unsaturated polyester resins can be further modified with hydroxy acrylates, other hydroxy terminated polyesters, and diisocyanates to produce resins with excellent water resistance and physical properties for various applications, such as marble/onyx resins, sheet molding compounds, bulk molding compounds and resin transfer molding resins, gel coats, and bowling ball resins.
